Just because I am a golf gear freak and a dork all in the same i think i made a mistake.  I bought some brand new fst pro125 shafts.  I didn't pay attention and come to find out these are .370 instead of .355.  First off i don't think i can get them to work in any of my Titleist iron sets or can i?  Second, does any know of any iron heads that these will work in.  I thought almost all of the iron heads are .355.  Thanks in advance for the help and God Bless!
